Abstract:
The invention relates to a drive arrangement for the electric adjustment of a functional element (1) in a motor vehicle. A drive motor (2), which adjusts the functional element (1) in an electrical manner in two adjustable directions, is provided and the drive motor is drivingly coupled to the functional element (1) by means of a first drive train (3) and a second drive train (4). The drive force is transmitted, simultaneously via the two drive trains (3, 4), at least in an adjusting device, during the electrical adjustment of the functional element (1). One of the two drive trains (3, 4) comprises a cable pull transfer (5) comprising a drive cable (6) which is used to transfer drive force. According to the invention, only one of the two drive trains (3, 4), primarily the second drive train (4), has a cable pull transfer (5) which is used to transfer drive force and the first drive train (3) is embodied in a cable pull free manner.

A chain operator housing (1) comprising a barrier member (16) for subdividing the interior of said operator housing (1) into an operator chain compartment, which is open to the exterior, and a drive compartment, which is substantially sealed from the exterior.
Abstract:
An electro-mechanical actuator (1) including a plurality of motors (2, 3) for driving an output shaft (10). The actuator may be incorporated into a window lift mechanism (30), such as a mechanism including a dual rack and pinion assembly (1314). According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e.g. clutches. A clutch according to one embodiment includes locking pawls (1616, 1618) that resist back-drive. In another embodiment, locking cams (2108) rotate relative to a carrier (2106) to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism (2616) including a flexible carrier (2618). The carrier (2106) flexes to prevent impact forces at an output gear train (2610, 2612) from coupling to an input gear train (2604, 2606).
Abstract:
The invention relates to an adjusting device having a high demultiplication, for example, two joint parts of a seat back adjusting system or of a control cable adjusting system. The inventive adjusting device comprises a first adjusting toothed wheel (1) provided a first adjusting denticulation area (5), a second adjusting toothed wheel (2) provided with at least one second adjusting denticulation area (6), an input shaft (3) provided with an input shaft denticulation (14), and two planetary toothed wheels, each of which comprising a planetary denticulation area. A first adjusting denticulation area is engaged with one planetary denticulation area of each planetary toothed wheel, and a second adjusting denticulation area (6) is engaged with a planetary denticulation area of each planetary tooted wheel. The input shaft denticulation (14) is engaged with a planetary denticulation area of each planetary toothed wheel or engaged with a first adjusting denticulation area of the first adjusting toothed wheel and with a second adjusting denticulation area of the second adjusting toothed wheel. A first adjusting denticulation area (5) of the first adjusting toothed wheel and a second adjusting denticulation area (6) of the second adjusting toothed wheel have different numbers of teeth and/or the planetary denticulation areas (15, 16), which are engaged with the first and second adjusting denticulation areas (5, 6), have different numbers of teeth.
Abstract:
A door closing apparatus for closing a hinged door (21) comprises a housing (10), a shaft (11) extending substantially along a longitudinal axis of the housing and being rotatably mounted therein. A connecting arm (22) is mounted at one end of the shaft (11) and extends transversely thereto. The other end of the connecting arm (22) is adapted to cooperate with a guide track (24), which is formed on the lower end surface of the door, so that the shaft (22) is moved from a first to a second rotational position, when the door is moved from an open to a closed position. The apparatus further comprises a spring (13) or other driving means for driving the shaft (11) from its first to its second rotational position and releasable locking means (19) for locking the shaft in its first rotational position. The housing (10) of the apparatus may be positioned in a recess formed in the floor. The locking means may lock the connecting arm (22) in its first rotational position, in which the door (21) is open, and when desired, for example in case of fire, the locking means may be manually or automatically released so that the door is moved to its closed position by the spring (13).
